I love talking about delusions, in a DSM IV medical kind of sense. What was the question?

I think that they point out some interesting aspects to beliefs, other than what I call opinions, stereotypes and conclusions (common beliefs like democrats are free spenders).
That along with memory tricks and damage is an interesting part of what makes for beliefs, not of the 'I believe that Newton’s law accurately describes the falling of an object in the earth's gravitational field.' sort of beliefs.
But the core biological basis what we perceive, have memories of and really believe to be reality.
People with delusions seem to have memories of events that did not happen, say they believe that they served in Europe in World War II, even though photographs, signatures, letters, companions and overwhelming amounts of evidence would indicate other wise. These beliefs are help firmly, confronting them has no effect on them, people may learn not to share them but they hold them to be true and valid experiences which they had.
Now this does lead to some interesting possibilities:
-that memory and experience are biological in nature and therefore subject to malfunctioning and spurious events. So perceptive events occur for the individual which are not related to actual events in the external world. Only in the brain.
-that somehow multiple realities exist and that a person may have a body but receives information from another reality (unlikely), but a correlate of the 'consciousness as TV signal' sort of theory.
And as intriguing as the second is the first seems more likely, in that in head trauma, memories are often confabulated, the person knows they were in the car but they believe they were headed to the store when they were heading home. (Beliefs countering evidence.)
Or in memory deficits such as dementia or Alzheimer’s, where consolidation of new memories do not occur, the individual has experiences that may no longer perceive as memories.
And this is where I think that the evidence for personhood as a biological process lies.
